[rules-users] Different knowledge bases Vs One knowledge base with use of agent filters..?

[Greg Barton]

If models can interact then the 2nd approach has advantages, and the advantages grow the tighter the interaction.  If they're independent then there's no need for the increased complexity of possible rule interaction, and the higher resource usage, especially if you're just running one model at a time.
